What is XHHW wire used for?
XHHW Wire Overview Wires with XHHW insulation are commonly used in the alternating current (AC) electrical distribution systems of commercial, institutional, and industrial buildings and installations, usually at voltage levels (potential difference or electromotive force) ranging from 110-600 Volts.
What is copper XHHW?
This copper building wire is intended to be used for general purpose applications in conduit, underground in conduit, or in any other recognized raceways for services, feeders, and branch-circuit wiring. XHHW wire is generally used for power distribution in residential, commercial, and industrial buildings.
What is the difference between XHHW and Thhn wire?
THHN/THWN-2 is a thermoplastic product, while XHHW-2 features thermoset insulation….HOW TO KNOW THE DIFFERENCE.
| THHN/THWN-2: | XHHW-2: |
|---|---|
| T = Thermoplastic | X = Cross-Linked Polyethylene (XLPE) |
| HH = High Heat Resistant | HH = High Heat Resistant |
| W = Water Resistant | W = Water Resistant |
| N = Nylon Jacket | (Not Required) |
Can XHHW wire be buried in conduit?
USE or URD is direct burial without any conduit if soil conditions permit. XHHW-2 is fine in conduit, just did the same myself but used #2 for 100A.
Can Thhn wire be used outdoors?
What Wire and Cable Should Be Used Outdoors? THHN is still the single conductor wire used outdoors and in conduit, because the THWN rating can resist water, oil, gases, and solvents.
Is XHHW better than Thhn?
Even though its jacket is thicker and more protective, XHHW is also more flexible than THHN wire. The XLPE insulation of the XHHW allows the cable to bend and flex better than the THHN’s PVC insulation—so XHHW is much easier to work with during the installation process.

Can you run service entrance cable underground?
From there, the transformer feeds two hot wires and a neutral to the service drop, either overhead or underground. Overhead and underground service entrances are both acceptable, though you may or may not have a choice as to which you have.
What is XHHW-2 wire used for?
XHHW-2 wire is the next generation XHHW wire. While its main use is for residential, commercial and industrial buildings, it is also used in raceways, feeder and circuit wiring. XHHW-2 is approved for use up to 600V and is UL Listed for 90° C (194° F), in both dry and wet locations.
Why is copper used for electrical wires?
Copper is a good conductor of electricity, it allows the electricity to flow through it easily. So copper is used to make connecting wires. Copper as a connecting wire has a very low electrical resistance. Copper combines several properties that have traditionally made it preferred for most electrical wiring.
What is a copper cable?
A copper cable is a group of two or more copper wires bundled together in a single sheath or jacket. Copper wire and cable is used in power generation, power transmission, power distribution, telecommunications, electronics circuitry, and countless types of electrical equipment.
